2017 UK Export Right Hand Drive Edge 2.0L Duratorq TDCi Diesel - Steering Locked with DTC U0131:00-AB Lost Communication With Power Steering Control Module (PSCM)

[Haz]

Welcome to the Forum @Ryan UK Edge 2017!

 

I understand from our Forum messaging that the new-to-you 2017 Edge presently is exhibiting locked steering with a scanner-revealed DTC U0131, indicating lost communication with the EPAS Steering Gear's Power Steering Control Module (PSCM).

 

Your Edge's vehicle history shows a related-repair effort recorded in Ford's Professional Technician System (PTS) in February 2024, about which you will eventually seek additional local feedback.

 

In the meantime, because of your personal technical capability and your need to move your Edge to a safer location, attached below and in an immediately following post are Workshop Manual and Wiring references in PDF format, to assist you toward fully diagnosis and possible correction of your Edge's locked steering...

your a diamond I’m just out with the car now I’ve put a battery that tested good on the car and still

presented the same issues I’ve just seen all

The pdf s I’ll download and print these 

 

I’ll be in touch thanks for your support in the issues 

[Haz]

Because the earlier repair effort involved the PSCM connector(s), you may want to examine them to ensure they are fully seated on the Steering Gear-mounted Module.

 

If they are fully seated, disconnect them and inspect for corrosion and/or for any pins that may have become pushed back inside the connector, and which could cause lost communication with the PSCM.

 

If subsequent scans reveal DTCs involving other modules, let me know here, and I'll provide additional Pinpoint Tests, which may involve checking circuit wiring for shorts or interruptions -- which the past repair efforts may have been pursuing.

 

Good luck!

when can you fly to the uk lol 

[Ryan UK Edge 2017]

Hi Haz 

 

i have printed all And start testing tommrow hopefully 

 

I was unable to see if there’s a part number for new PSCM unit 

 

also do you know if Forscan can read PSCM and possible recode it

 

thanks again 

 

Ryan 

[Haz]

You will need at least a temporarily licensed copy of Forscan to reprogram a new PSCM with the appropriate As-Built data, which you can either copy from the currently installed PSCM, or verify that the PSCM contains the programing values shown in the As-Built Reprograming Data listing that I provided via Forum messaging. If you refer to the Module Configuration Workshop Manual document, the numerical line address for the PSCM will be shown in the table of various modules.

 

Regarding a PSCM part number, I have not yet been able to find a replacement part number listed. I'm aware that the Steering Gear Removal and Installation Workshop Manual document indicates the PSCM provided with a new Steering Gear assembly must be appropriately programed with As-Built values obtained from the prior PSCM before it is removed. To me, this indicates the PSCM is provided in the assembly (PIA) replacing the faulty Steering Gear. On the other hand, one of the diagnostic procedures indicates "Replace the PSCM" as if the module can be separately obtained and is replaceable on the Steering Gear assembly, but again, I've not found a Service part number for the PSCM.

 

Working from illustrations and based upon the depicted connector receptacles, I expect the PSCM is located in the area bounded by red arrows here...

 

etho

 

The full view of this cropped illustration is zoomable and scrollable using your web browser here.

 

Neither the UK nor the North American Edge Workshop Manuals include any PSCM removal and installation procedure, which is unusual.

 

If your diagnostic effort indicates PSCM replacement, then hopefully, inspecting your Edge's Steering Gear may yield a part number stickered or printed on its PSCM, along with some obvious module-mounting fasteners. Lacking Workshop Manual guidance, the question remains of how the PSCM interfaces with the Steering Gear assembly -- unless it's only via the laterally installed harness shown in the Steering Gear illustration, likely containing a C1463A or C1463B connector .

 

Good luck!

Thanks Haz

 

yes im glad to here that it’s not just me that cannot locate the data on PSCM location or part number I may call ford to ask for the part detail I’ve got enough data from yourself to proced

 

I paid for full forscan for a year and have the plug in obd switch required so will try with forscan to scan the PSCM 

[Ryan UK Edge 2017]

Hi Haz

 

hope your well 

immthinking that’s black box ontop

of the gear/ motor may be the PSCM module

unit 

[Haz]

I agree, and I too, just found 2017 Edge Steering Gear photos...

 

 

 

 

I also found a possible PSCM part number on a VIN-specific report, via Ford's UK Professional Technician System (PTS) website: F1GC-3F964-BA. It is possible that then current Service replacement has a different part number, so consulting with your local Ford Works dealer is necessary.

 

Just for awareness, you could verify the part number, cost and availability, though the only DTC thus far is no communication -- which can involve connector, wiring, ground faults.

 

If a DTC for internal failure of the module was present, it would be clear-cut that investing in a new PSCM is the right option -- presuming it's available apart from the Steering Gear assembly.

 

I'll supply that VIN-specific report to you via Forum messaging.

 

Good luck!

 

[Ryan UK Edge 2017]

Thank you sir 

 

for Your ongoing support on my issue 

 

I will as the Machanic to 

access the rack check connections for damage , water ingress etc 

 

I’ll have my laptop with forscan for Tuesday day and I’ll look at what the software can tell me I’ll speak with the dealer tomorrow also 

 

thanks 

 

Haz 

[Ryan UK Edge 2017]

The part number hardley returns any replacement parts so may be a superseded part also 

[Ryan UK Edge 2017]

Is there anyone on forum

that would have a clue how ro

possibley disengage - bypass the steering lock to release it so I can move the car it starts drives but steering lock is locked on so only can go back

or forwards till I can figure out this module issue 

 

surely it’s engaged electronically 

 

please someone must know a work around

System Diagram - Steering Column Lock (if equipped)

 

Network Message Chart - Steering Column Lock (if equipped)

  BCM Network Input Messages

 

Broadcast Message	Originating Module	Message Purpose
Engine rpm data	PCM	Provides the BCM with the engine speed to indicate if the engine is running or not.
Wheel rotation count	ABS module	Provides the BCM with the vehicle speed to indicate if the vehicle is moving or stationary.

Steering Column Lock (if equipped)

The steering column lock is used to deter vehicle theft by electronically locking the steering column. This prevents the steering wheel from being rotated to turn the front wheels.

 

The steering column unlocks when:

• the passive entry feature is used to open the driver door.
• the driver door is opened after unlocking the vehicle with a RKE transmitter.
• the START/STOP button is pressed and a valid programmed passive key is detected.
• the remote start feature is activated.

 

The steering column locks after:

• the ignition is turned off and 45 seconds have elapsed since the delayed accessory feature has turned off.
• 45 seconds have elapsed since the remote feature turned off the vehicle.

 

The BCM controls the voltage provided to the steering column lock module using a relay (located in the BJB ) and communicates with it over a LIN .

 

The BCM monitors inputs from various systems to determine when to send a command to lock or unlock the steering column. The steering column lock module locks and unlocks the steering column as directed by commands received from the BCM .

 

If the BCM detects a fault from the steering column lock module or the LIN , the BCM prevents the vehicle from starting.

 

The BCM does not provide power to the steering column lock module when the vehicle is moving or the engine is running.

 

Steering Column Lock Messages (if equipped)

The message center displays a message when the BCM detects a fault from the steering column lock module.

 

The "Steering Malfunction" message displays when a fault with the electronic steering column lock system is present and must be diagnosed.

 

The "Turn the wheel while starting" message displays when the steering column lock module is unable to unlock the steering column because of a high amount of torque against the lock (such as when the wheels are against a curb when the vehicle is shut off). The torque against the steering column lock must be relieved for the steering column to unlock.

 

Turn the vehicle off, rotate and hold the steering wheel in one direction while turning the vehicle on. If the message displays again, turn the vehicle off, rotate and hold the steering wheel in the other direction while turning the vehicle on.

 

Component Description

 

Steering Column Lock Module (if equipped)

The steering column lock module locks and unlocks the steering column based on commands received from the BCM . The steering column lock module monitors the position of the steering column lock and, if a fault is detected, reports the failure to the BCM .

 

When the steering column lock module is replaced, the BCM must configured/trained to the new steering column lock module for the steering column lock module to operate correctly.

 

The BCM sets a DTC if a fault is detected with the steering column lock module. Additionally, if the BCM is not configured to the steering column lock module, the steering column module keeps the column locked, a programming and/or configuration DTC sets and the vehicle does not start.
